In this paper. we propose a fiber-optic time synchronization technique based on the bidirectional wavelength division multiplexing (WDM) transmission over a fiber link. The effect of fiber dispersion on the uncertainty of the system is effectively suppressed by properly allocating the forward and backward wavelength maps. Thus. https://www.pomyslnaszycie.com/laguna-3hp-c-flux-cyclone-dust-collector-on-sale/
